' IMPROVEMENT IN HYDRANT-VALVES.

Specification forming part of Letters Patent No. 200,162, dated February 12, 1878 application filed January 23, 1878. a

.such as will enableothers skilled in the'art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in hydrant-valves; and it consists in the arrangement and combination of parts whereby allof the waste-water is forced upward through the discharge-pipe, leaving no water to remain in the waste-water chamber, so as to freeze in the winter, and in locating the waste-water chamber below the water-main, so as to be beyond the reach of the frost, as will be more fully described hereinafter.

Figure 1 represents a vertical section of my invention. Fig. 2 is a horizontal section through the cover.

(t represents the waste-chamber, which is preferably made cylindrical in form, and of any desired size that may be preferred. This chamber is located below the level of the water-main, so that the waste-water cannot freeze therein in very cold weather. The water passes through the opening I), in the upper end of this chamber, into the small chamber 0, formed upon one side of the wastewater chamber. From this chamber 0 the water passes upward through the small openings (1, formed in the top of the waste-water chamber a, into the chamber 6, formed upon the'top of the nut or cover g, which closes the top of the chamber a. In the top of the chamber a, and in the under side of the nut g, are formed one or more suitable grooves, i, through which the water can freely pass in case the chamber 0 (upon the side of the cylinder to) and the chamber 6 (upon the side of the nut) should not come together when the nut is screwed into position. By means of this groove it is immaterial, in screwing the nut 9 into position, whether the chambers e 0 come together or not, for the water will pass as freely through the groove as it would if the two chambers were together. From the chamber e the water passes inward through. the nut or cover 9, through the holes made into the nut j, which screws down into the cover g. Around the outside of this nut j is made a groove, 1, so that when the water passes through the cover y it will at once pass all around the nut j, and enter through the many openingsn, made through the nut. Instead of the many holes n here shown,-but a single slot may be made througlrthis nut for the passage of the water, which will answer the same purpose equally as well.

Upon the top of this nut j is screwed the nut m, which tightens the washer down upon the top of the cover g, so as to prevent any upward leakage of water. Passing down through the center of the nut j is the supply-pipe p, which plays vertically up and down through the nut, as shown. In the upper part of the nut j is formed a packing-box, for the purpose of forming a tight joint where the pipe 1) passes through, and thus preventing leakage of the water.

Upon the lower end of this supply-pipe or water-way p is secured a suitable plunger or piston, q, of leather or any other suitable material, which fits the cylinder to water-tight, and serves to lift or discharge all the wastewater which has run from the pipe 1) and valve into this chamber. Through the lower end of the pipe 1) are made a number of holes, through which the water in the pipe or valve, after the water has been cut off, escapes into the chamber a above the piston.

Instead of the number of small holes here shown, a single slot may be used, if so preferred. When the water is shut off, this pipe 1) is depressed downward into the chamber a; but when it is desired to draw water, the pipe is raised upward by any suitable mechanism until the holes or hole in its lower end comes just opposite to the holes or hole made through the side of the nut j. When the holes in the pipe 1) come just opposite the holes in the nut j the water passes freely through the two chambers c 0, through the nut or cover g, and through the nut j into the pipe, and thence on up to the discharge.

As soon as the water is cut off the pipe 12 is IGHT ' depresseddownward below the holes in the nut j, wheniallthe'water that is left in the pipe '1) at once runs'into the waste-chamber As soon'as Water is again drawn from'the Z hydrant, the upward lift of the'pipe 19 serves first to empty all this waste-water before any fresh water can pass into the pipe, and then 7 each time that thehydrant is usedthe Waste:

7 7 Water isdiseharged from the cylinder by the 1 upward movement of the piston. V r V V Z By the V arrangement of parts above de scribed there will be no water leftin the chain her to: freeze,and the valve will 'always be Vkept'dry-upon both the inside and the outside whenthe hydrant isin use. N0 water can leak from the valve into the stock or ground,

-nor will any Water remain in the stock to freeze afterthe water has been shut off.

{Should the packing at any time become loose and need repairing from Weanthe Waste-Water will rise to the topof the pipe 2, and, by its 7 escape at the discharge, indicate that repairs are necessary. 7 7

Although the cover gand the nut j are here shownas two separate and distinct parts, in practice they may be 'made in a single cast 7 ing, so as to makethem both'cheaper and simpler in construction, and in which case 7 1 there will be an opening made directly through to the pipe 11 from the chamber 6, so as to let a the water flow direct to the pipe.

Having thus claim- 7 1;. The combination of the Wastewater chamber 41;,having a chamber, a 6, formed at the tically-adjustable pipe 12, having'a' hole or holes through its lower end, substantially as J 'setfortha'" or 3. The combination of the vertical adjust- V r I able pipe'p, having a hole or holesthrough its lower end, and a piston orplun ger attached thereto, waste-Water chamber a, nut j, cover g,

chambers c e, and connecting grooves, all ar ranged to operate substantially as and forthe purposes specified, 7

In testimony that I claim the foregoing I have hereunto set my hand this 22d day of n January, 18 78. V r r V J. BAINS.
